As the Twitter co-creator returns to activism, his fellow hackers question the techniques he brings from Silicon Valley.

Synopsis

Evan "Rabble" Henshaw-Plath is a coder, activist, anarchist, and a hacker. He is also one of the original developers of Twitter.

Henshaw-Plath believes that, as a tech activist, his role is to promote social justice, and he is eager to empower civil society to influence politics through the use of software. He explains how TxTMob, a platform that enabled protesters to send text messages to large groups anonymously, formed the basis of Twitter.

Now bridging the worlds of hackers, activists and Silicon Valley start-ups, he's on a mission: to use techniques he has learned in the world of lean start-ups to support the technology being developed by activist groups.
